Steps to Build a Quote Generator in Excel
1. Set Up the Pricing Database
Create a worksheet to maintain a database of your services, materials, and rates. Include details like hourly rates, material costs, and markups.
Example Table: Pricing Database
| Item ID | Description | Unit | Cost Price | Markup (%) | Charge Price |
|---|---|---|---|---|---|
| H001 | Labour (Hourly Rate) | Hour | $50 | 100% | $100 |
| M001 | Timber (per unit) | Unit | $15 | 50% | $22.50 |
| M002 | Paint (per litre) | Litre | $10 | 80% | $18 |
- Use formulas like
=Cost Price * (1 + Markup)to dynamically calculate charge prices. - Include categories (e.g., Labour, Materials) for easier organisation.
2. Create the Quote Template
Set up a professional quoting template that can auto-populate data based on inputs.
Steps:
- Dropdown Selection: Use Data Validation to allow users to select items or services.
- Dynamic Calculations: Use
VLOOKUPorXLOOKUPto fetch prices and descriptions from the pricing database. - Custom Quantities: Add input fields for quantity, automatically updating totals.
Example Table: Quote Template
| Item ID | Description | Quantity | Unit Price | Total |
|---|---|---|---|---|
| H001 | Labour (Hourly Rate) | 10 | $100 | $1,000 |
| M001 | Timber (per unit) | 20 | $22.50 | $450 |
Quote Total: Use SUM to calculate the grand total, including GST if applicable.
3. Add GST and Customisations
For Australian businesses, ensure GST (10%) is factored into quotes.
- Add a row for GST:
=Total * 0.10. - Include an "Adjustments" row for discounts or additional charges.
Example:
| Subtotal | $1,450 | | GST (10%) | $145 | | Total | $1,595 |
4. Track Quotes and Jobs
Create a transaction log to record issued quotes, job statuses, and payments.
Example Table: Quote Log
| Quote ID | Customer Name | Date | Total | Status |
|---|---|---|---|---|
| Q001 | John Smith | 01/12/2024 | $1,595 | Accepted |
| Q002 | Jane Doe | 02/12/2024 | $800 | Pending |
- Use dropdowns for status updates (e.g., "Pending," "Accepted," "Declined").
- Assign unique IDs for each quote to maintain an organised record.
5. Build a Job Costing Summary
For subcontractors, track costs and margins for each job.
Example Table: Job Costing Summary
| Job ID | Labour Cost | Materials Cost | Overheads | Total Cost | Revenue | Profit Margin |
|---|---|---|---|---|---|---|
| J001 | $1,000 | $450 | $100 | $1,550 | $1,595 | 2.9% |
- Use formulas to calculate profits:
=Revenue - Total Cost. - Add fields for overheads and additional expenses.
6. Create Dashboards for Insights
Build dashboards to visualise your data, helping you manage clients, jobs, and financial performance.
Examples:
- Customer Dashboard: Revenue and job history by client.
- Job Dashboard: Profitability by job or trade category.
- Monthly Summary: Total revenue, expenses, and profit margins.
Tools:
- Use PivotTables and PivotCharts for summaries.
- Add slicers for easy filtering by client, trade, or time period.
Key Features to Include
- Templates: Pre-designed sections for common trades (e.g., carpentry, plumbing).
- Conditional Formatting: Highlight quotes nearing expiry or overdue payments.
- Macros: Automate repetitive tasks like generating PDFs or sending emails.
